- End of the flat spot under full throttle claimed
- Five modes for different situations
- Pack in as much as an extra 40kW
Did you know that there’s as much as 110Nm more torque lurking in the D-TEQ engine of your Isuzu KB300? There is, according to Steve’s Auto Clinic.
SAC says a “Lekker Ou Jan” performance upgrade will release it with Unichip’s PowerPlug for the Isuzu’s D-TEQ 3.0 turbodiesel engine.
It also claims to reduce fuel consumption.
SAC says it has programmed the Unichip Q4 to monitor and control multiple aspects of the engine simultaneously, while “off the shelf” performance chips simply increase fuel-pressure while ignoring engine coolant temperature or boost pressure.
“The Unichip Q4 / PowerPlug plug-and-play combination,” SAC says in a media release, “precisely controls fuel pressure and boost pressure with a timer control. It also allows certain maps to override the fuel-injector settings for reduced fuel consumption. The Unichip also monitors engine temperature and maintains it within its safety parameters while still delivering more power.”
Stephen Fischer, founder and CEO of the SAC Group, said: “With the ‘Lekker Ou Jan’ upgrade the difference in engine performance will be immediately evident – an improvement of 30-40kW in engine power to as much as 170kW and a jump in torque from 380Nm to around 490Nm.”
The upgrade includes a power switch which allows the driver to change performance maps on the fly – five are programmed into the upgrade.
The first removes all engine power and ensures an additional layer of security when the vehicle is parked. The driver simply takes the switch with him; the vehicle will be almost impossible to drive.The second returns your Isuzu D-TEQ to standard, with no change in performance or fuel consumption, the third changes engine characteristics and performance to dramatically reduce fuel consumption.
Fischer again: “By optimising engine performance the driver should use less fuel in all settings; in fuel-consumption mode the saving can be as much as 15%, depending on environmental conditions and driving style.”
The remaining two maps, SAC claims, offer the best in engine optimisation. One is a 4×4 and towing setting which optimises torque delivery at low engine revolutions for technical off-road driving or for towing a heavy load – said to be ideal for those who chose the Isuzu for its high load and tow ratings.
The final setting, SAC says, will deliver all latent power “to give the driver a very rewarding experience while maintaining engine durability and safe operating conditions”.
There is also a throttle boost option which, it’s claimed, will ensures smooth acceleration and better throttle response, regardless of engine speed – removing a perceived flat spot experienced by many D-TEQ owners under hard acceleration.
“We chose the name ‘Lekker Ou Jan’ to pay homage to the trusty old plaasbakkies that we all know,” Fischer added. “From early days Isuzu established itself as a manufacturer of trusted, reliable, bakkies and the KB300 remains a very popular option. Now we allow owners to dramatically improve their driving experience, reduce fuel consumption and improve performance without losing the reliability for which the bakkie has become known.”
